ISO 15552 Pneumatic Cylinders: FMY Series

ISO 15552 fixes the mounting dimensions, rod sizes and rod-end threads of pneumatic cylinders from Ø32 to Ø320, so a cylinder from one maker can replace another's without changing the machine.

Fenitsa's FMY series follows ISO 15552 with magnetic piston and adjustable cushioning across the full Ø32–Ø320 range.
